|
|
|
The nutritional composition of Korean native black cattle (KNBC) and Hanwoo beef were compared. According to the results, there were no significant differences in moisture, protein, ash, calorie and collagen content, but the fat content of KNBC was significantly higher than that of Hanwoo (p<0.05). The P, Na and Cu content of KNBC were significantly higher than that of Hanwoo (p<0.05). The KNBC and Hanwoo had total mineral amounts of 4,052.34 and 3,214.44 ppm, respectively, with the KNBC being significantly higher than Hanwoo (p<0.05). The vitamin B1 content of KNBC was significantly higher than that of Hanwoo (p<0.05), but there was no significant difference in B2 content between the samples. The total structural amino acid contents was not significantly different between KNBC (12.35%) and Hanwoo (12.58%). The KNBC and Hanwoo had total free amino acid amounts of 752.698 and 661.795 ppm, respectively, with the KNBC being significantly higher than Hanwoo (p<0.05). The stearic acid (10.631%), linoleic acid (2.271%), linolenic acid (0.065%) and tricosanoic acid (0.038%) contents of KNBC were lower than those of Hanwoo (p<0.05). However, their palmitoleic acid (5.292%), oleic acid (48.815%), γ-linolenic acid (0.094%), eicosenoic acid (0.042%) and docosadienoic acid (0.099%) contents were higher than those of Hanwoo (p<0.05). There was no significant difference between the KNBC and Hanwoo in the saturated fatty acid : unsaturated fatty acid ratio.
